The type specimen consists of the apical three-quarters of a fore 
wing, moderately well preserved; the details of venation and of the 
cross veins have been worked out by the application of alcohol and 
glycerine to the specimen. 
The similarity of the preserved part of this wing to the fore wing 
of Dictyoptilus is very striking (see Figures 4A and 4B). It is 
becoming increasingly clear that the apparently local distribution of 
the families of Palaeozoic insects has been largely the result of the 
distribution of collecting patterns. The families were probably just 
as widely distributed as most families of insects at the present time. 
Order Caloneurodea 
Family Permobiellidae Tillyard 
This family, which has previously been found only in the Lower 
Permian deposits of Kansas, is characterized by having the subcosta 
terminating at about mid-wing, by having three branches on the 
radial sector and by having CuA and CuP close together proximally 
but diverging distally. Only the genus Permobiella Tillyard, with 
its type species perspicua Tillyard, is known ('Carpenter, 1943). 
The fossil from New Mexico appears to belong to this family. It 
clearly has the relatively short subcosta and the three-branched 
radial sector. CuA and CuP are close together proximally but since 
CuP is not preserved distally, its terminal relationship to CuA is 
unknown. The general venational pattern of the specimen from New
